It feels like the power steering goes out for a second or two. NOT A GOOD FEELING. And it's happened since I had a completely new front suspension (all synergy: trac bar, tie rod, drag link, ball joints, trac bar and steering sector shaft brace) and a fresh alignment on a brand new alignment rack.
I can assure you the power steering wheel system IS affected by ESP or ESC or whatever electronic bs is in place.
2012, 6 speed, AEV 3.5", 35's, procal, etc
And I can assure you that spinlock is correct. As far ESC goes it only applys selective bracking individuals wheels. There is no electrically control mechanism in the steering system capable of interfering with the steering system. The power steering pump is mechanically powered and the steering system is mechanically connected the steering box. For the steering to be impacted it would need to be steer by wire or have a braking system somewhere in the steering system, does not exist.
ESC exist on many vehicles including my Vette. ESC can not over come physics though. If the slide is big enough you are going to go around. Driving with ESC though is a different skill than driving without and means over coming skills learned without the system.
Unlike conventional skills, counter steering in a slide with ESC you want to continue to hold the turn. The reason for this ESC uses the steering posistion sensor to determine what you want to do. If you counter steer and then ESC kicks in you will most likely end up end up going a direction you did not intend to go.
Like anything else it takes practice and understanding to live with ESC. If you are wheeling or playing in the snow by all means disable it. But for normal driving or driving in wet conditions if you understand it, it works very well. In fact it works so well that when I race the Vette in wet conditions I keep it on.
